Select ALL the plate boundaries where rifting that eventuall results in sea floor spreading occurs: transform plate boundaries. divergent plate boundaries. convergent plate boundaries. Sea floor spreading does not take place at plate boundaries.
The crust floating above the asthenosphere creates the plates when it breaks. The edges where the two plates meet makes up a plate boundary. The geologic activities such as volcanic eruptions, mountain building, and earthquakes all occur at such boundaries. There are three types of plate boundaries:
Convergent plate boundaries, also known as the destructive plate boundaries, divergent plate boundaries, also known as the constructive plate boundaries, and transform plate boundaries.
The new crust is created along the divergent plate boundaries. These boundaries occur where rifting occurs. It can also be said that this is the areas where two plates move away from each other form divergent plate boundaries like mid-oceanic ridges. The seafloor spreading occurs along mid-oceanic ridges as rifting occurs here.
Hence statement ‘2’ is correct.
